1. A system for safely removing a tissue specimen through a body opening, the body opening defining a tissue margin, the system comprising:
a retractor having a first ring and a second ring interconnected by a sidewall defining a central lumen having a top opening and a bottom opening; the second ring being compressible into a low-profile configuration for insertion through the body opening and the first ring having a first ring diameter; the retractor being configured such that the sidewall can be rolled up around the first ring to reduce a length of the retractor and to retract the tissue margin;
a shield made of cut-resistant material including a proximal end and a distal end interconnected by a sidewall; the shield having an inner surface and an outer surface and an elongate tubular-shaped working channel extending from the proximal end to the distal end along a longitudinal axis; the shield having a proximal flange at the proximal end that extends radially outwardly from the longitudinal axis to define an outer diameter at the perimeter of the proximal end;
wherein the shield is sized and configured to be removably connected to the retractor when the retractor is placed across the body opening and the shield is inserted into the central lumen of the retractor;
wherein the shield is split from the proximal end to the distal end to define a first end and a second end; and
wherein each of the first end and the second end of the shield includes an S-shaped curvature configured to overlap onto an outer surface of an adjacent shield portion when in a relaxed configuration.
